An equimolar saturated liguid-saturated vapor mixture containing 35% A, 65% B in moles at a flow rate of 100 kmol/h will be separated by distillation. It is desired that 93% of A is present in the top product and 96% of the A entering the column is in the top product, If the reflux ratio in the column is 4 and the relative volatility & = 2, determine the given below; a) Theoretical number of plates and feed plate (20p) b) Top and bottom product flow rates (10p) c) Minimum reflux ratio (10p) d) Minimum number of plates, (10p)
